Claim super-deduction and deal with asset disposals where super-deduction has been claimed in Corporation Tax

Super-deduction

The 2021 Budget introduced super-deduction for expenditure incurred by companies between 1 April 2021 and 31 March 2023. These changes are summarised in HM Revenue and Customs Guidance: Super-deduction:
From 1 April 2021 until 31 March 2023, companies investing in qualifying new plant and machinery assets will be able to claim:
  • a 130% super-deduction capital allowance on qualifying plant and machinery investments
  • a 50% first-year allowance for qualifying special rate assets
[Super-deduction]
To find out more, refer to HM Revenue and Customs Guidance: Check if you can claim super-deduction or special rate first year allowances.
HM Revenue and Customs added boxes to the 2022 CT600 for super-deduction. Corporation Tax versions 22.0 and 23.0 contain these boxes for super-deduction, but do not automatically write back to these boxes. We intend to add this function later. Until then, you can use the following alternative method to add the rates manually.

    1. Go to
      Capital Allowances
      .
    2. Select
      Assets
      .
    3. In the

  8. Enter the
    Proceeds
    amount (this is the balancing charge for the asset you calculated earlier).
  9. Select
    Calculate Allowance
    .
  10. If the disposal is of an asset where the Special Rate First Year Allowance has been claimed at 50% or where the allowance was not claimed in full, you'll need to go to the Special Rate Pool (or General Pool) and dispose of the portion of the asset in that pool.

    2. Enter the balancing charge in one or both of these boxes, as needed.
    3. Select box
      730
      and either press
      Space bar
      to remove the amount or, if there should be other items in the box, replace it with the correct amount.

Add a note if you applied the alternative method in version 21.2 or earlier

    Capital Allowance Explorer
    .
  2. Select the pool folder.
  3. Select
    Notes

    .
  5. Select
    Close
    , then
    OK
    .
When you next open the computation, the note will show under the relevant pool section.
